We also conducted on-site internal audits at our overseas manufacturing sites (Korea, China, Philippines, and Malaysia) (in FY2021, we conducted them remotely due to COVID-19). All 33 issues pointed out have been corrected. Regarding non-conformities, we create corrective action plans (including root causes, improvement measures, preventive measures, deadlines, etc.) and work to reduce risks.
